Abstract (en)
The invention relates to chemically resistant structures that float on top of a liquid to reduce the level of evaporation from the liquid. The liquid could be in a small container or vat, or in a larger pool, pond, or reservoir. The structure is preferably a foamed material of a polyamide or fluoropolymer, or may be a hollow or foamed structure having a polyamide or fluoropolymer outer layer. The structures covering the liquid may consist of a single structure or two or more discrete structures that partially or fully cover the surface of a liquid. The covering is especially useful where the fluid contains toxic, reactive or corrosive substances. One preferred structure is a polyvinylidene fluoride foam structure (such as a KYNAR from Arkema Inc) at about 0.1 - 36 inches in length/diameter.
